Adding GST_CUDA_CRITICAL_ERRORS env variable so that program can be terminated on unrecoverable error. Example) GST_CUDA_CRITICAL_ERRORS=2,700 gst-launch-1.0 ... In this example, CUDA_ERROR_OUT_OF_MEMORY(2) and CUDA_ERROR_ILLEGAL_ADDRESS(700) are registered as critical error and program will be aborted on those errors Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/4729>

# Cuda library
|
|
|
|
This library should be linked to by getting cflags and libs from
|
|
gstreamer-cuda-{{ gst_api_version.md }}.pc
|
|
|
|
> NOTE: This library API is considered *unstable*
|
|
|
|
## Environment variables
|
|
|
|
The GStreamer CUDA library inspects following environment variables
|
|
|
|
**`GST_CUDA_CRITICAL_ERRORS`. (Since: 1.24)**
|
|
|
|
This environment variable can be set to a comma-separated list of CUresult
|
|
values (see CUDA driver API documentation). GStreamer CUDA library will
|
|
abort when the user registered error is detected. This environment can be useful
|
|
when unrecoverable CUDA error happens. Thus in-process error recovery
|
|
(e.g., relaunching new pipeline) is not expected to work, and therefore
|
|
the process should be relaunched.
|
|
|
|
Example: `GST_CUDA_CRITICAL_ERRORS=2,700`
|
|
|
|
As a result of the above example, if `CUDA_ERROR_OUT_OF_MEMORY(2)` or
|
|
`CUDA_ERROR_ILLEGAL_ADDRESS(700)` error is detected in GStreamer CUDA library,
|
|
the process will be aborted.
